I need help with a way i can go about this question in matlab ( a code to calculate).

Based on the information about the image subbands, complete the Fun_1LevImDecomp function to perform a single-level image decomposition into the A,H,V, and D subbands (Fig. 9). The function takes the original image as an argument and returns the image of the same size being a composite of image subbands. The function is called from the Lab_08.m script. Inside, you can find comments with some tips on the sequence of operations. Use as simple decomposition filters as possible. The function can display the intermediate results in a separate window. WARNING: you cannot use a ready-made function such as dwt2 or wavedec2. The function should work with any image size. To verify its operation at the second level of the wavelet analysis of the image, uncomment the second part of the code in Task \#2 block within the Lab_08.m script. After this task is completed, upload the file with the completed function on the DEP
